Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a connector structure that combines pins and claws. Background Technology

[0002] The socket on a conventional connector typically includes a socket housing, a cover plate connected to the socket housing, claws, and pins. During assembly, the claws are first fitted onto the pins, and then the pins are inserted into the cover plate and the pin housing. To prevent the claws from moving axially during the insertion of the pins into the cover plate and the pin housing, an annular groove is usually machined on one side of the annular protrusion on the pin, and the claws fit into the annular groove. Machining an annular groove on the pin increases the manufacturing process and production costs. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a connector structure that combines pins and claws to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a connector structure combining a pin and a claw is designed, comprising: a socket, the socket comprising: a socket housing, a cover plate, a claw, and a pin, the socket housing having a receiving groove and a through hole at the bottom of the receiving groove, the cover plate having a through hole and a mounting hole below the through hole formed by injection molding, the claw being engaged in the mounting hole, the claw having an elastic buckle inside, the cover plate being inserted into the receiving groove, and the claw being located above the bottom surface of the receiving groove, the lower end of the pin being inserted into the through hole, and the annular protrusion in the middle of the pin being located between the elastic buckle and the bottom surface.

[0006] Using the above technical solution, during the injection molding production of the cover plate, through holes and mounting holes are directly injection molded inside. When the socket is assembled, the claws are engaged in the mounting holes, and the cover plate is inserted into the receiving groove on the socket housing. The upper sidewall of the mounting hole and the bottom surface of the receiving groove can restrict the up-and-down movement of the claws. When the pin is assembled, the lower end of the pin is inserted into the cover plate and passes through the claws into the socket housing. During the movement of the pin, its annular protrusion abuts against the elastic buckle inside the claw, causing it to unfold. When the annular protrusion moves below the elastic buckle, the elastic buckle resets. At this time, the annular protrusion in the middle of the pin is limited between the elastic buckle and the bottom surface to restrict the up-and-down movement of the pin. In this solution, the pins of the socket do not need to be machined with annular grooves, reducing manufacturing processes and relatively reducing production costs.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, the claw is a circular elastic structural member with a through-slit on one side, and multiple elastic buckles are distributed around its inner circumference.

[0009] In some embodiments, after the claw is placed in the mounting hole, its outer sidewall abuts against the sidewall of the mounting hole. When the claw is not placed in the mounting hole, its circumferential circular outline is larger than the diameter of the mounting hole. When it is necessary to place the claw in the mounting hole, pinching the claw to narrow or close the through-gap on it can reduce its circumferential circular outline before it can be placed into the mounting hole. After releasing the claw, it abuts against the sidewall of the mounting hole under the action of its elastic restoring force, thus achieving installation. The abutment can prevent the claw from falling off when the cover plate is assembled with the socket housing, which facilitates assembly.

[0010] In some embodiments, the outer wall of the cover plate is provided with multiple snap-fit ​​fasteners, which engage with multiple slots on the side wall of the receiving groove. This snap-fit ​​installation method allows for rapid assembly.

[0011] In some embodiments, the lower end of the through-hole is provided with an annular anti-touch protrusion, and the lower end of the pin is located above the anti-touch protrusion. If accidentally placed at the lower end of the through-hole, the anti-touch protrusion prevents contact with the pin, improving safety.

[0012] In some embodiments, the socket housing is provided with U-shaped connection holes at the left and right ends, and a sealing ring is installed in the groove in the middle.

[0013] In some embodiments, the bottom of the cover plate is provided with a slot, and the socket housing is provided with a plug plate that is inserted into the slot. Attached Figure Description

[0025] The socket housing 1 is injection molded with a receiving groove 11 and a through hole 12 located at the bottom of the receiving groove 11. Two, three, four or more slots 13 are provided on the side wall of the receiving groove 11, and the number of slots 13 is set as needed.

[0026] The cover plate 2 has a through hole 21 and a mounting hole 22 located below the through hole 21, both at the top and bottom. Figure 3 Based on the indicated orientation, the diameter of the mounting hole 22 is larger than the diameter of the through hole 21. The outer wall of the cover plate 2 is provided with multiple buckles 23, and the number of buckles 23 is the same as the number of slots 13.

[0027] The claw 3 is a circular elastic structural component with a through gap 31 on one side. Its material is phosphor bronze, tin bronze, silicon manganese spring steel, etc. Two, three, four or more elastic buckles 32 are distributed around the inside of the claw 3. The number of elastic buckles 32 is set as needed. The claw 3 is inserted into the mounting hole 22, and its outer side wall abuts against the side wall of the mounting hole 22.
